PFC (Power Factor Correction)

Integrated circuits, or ICs, are tiny electronic circuits that are made up of transistors, diodes, and other components. They are called "integrated" because all of these components are combined into a single chip, which can be as small as a few millimeters in size. Power management integrated circuits, or PMICs, are specialized ICs that are designed to manage and regulate the power supply in electronic systems. They are often used in portable devices, such as smartphones and laptops, where power consumption and efficiency are critical. Power factor correction, or PFC, is a technique that is used to improve the power factor of an AC electrical power supply. Power factor is a measure of how efficiently electrical power is being used, and a low power factor indicates that the power supply is not operating at full efficiency. PFC circuits are used to correct the power factor by adjusting the phase and magnitude of the current and voltage in the power supply, which can improve the efficiency and reduce the amount of power wasted. This can help to reduce energy costs and improve the performance of electronic systems.
